A First-Ever Standard Lands for Steam Boiler Makers

New EU harmonised standards for small steam sterilizers and stainless steel boilers simplify MDR conformity across Europe

4 Jun 2026

Two updated harmonised standards for steam sterilization equipment have been added to the EU's Medical Devices Regulation framework, offering manufacturers a more defined route to market compliance.

Published in the Official Journal on 7 April 2026, Commission Implementing Decision (EU) 2026/760 revises the list of standards recognised under the MDR. EN 13060:2025 replaces an earlier standard for small steam sterilizers used in medical, dental, and veterinary settings, incorporating updated requirements for cycle validation, performance testing, and equipment safety. EN 14222:2021+A1:2025, covering stainless steel steam boilers, becomes the first harmonised standard for that product class under the MDR.

Under Article 8(1) of the MDR, conformity with a listed harmonised standard grants presumption of compliance with the corresponding general safety and performance requirements. Manufacturers can rely on that presumption during conformity assessment, rather than constructing separate evidence for each requirement. For stainless steel boiler makers, this resolves a gap: the product class previously had no approved regulatory reference point under the MDR.

Smaller manufacturers are likely to feel the most immediate effect. Notified body assessments have grown more demanding since full MDR enforcement began, and any mechanism reducing compliance uncertainty lowers both cost and time at the certification stage.

A formal standardisation request from the Commission to CEN and Cenelec, Europe's technical standards bodies, initiated the update, directing both organisations to revise existing standards in line with current engineering and scientific practice.

Manufacturers should now determine whether the new standards apply to their product lines, review the implications for technical documentation and test protocols, and engage with their notified body before transitioning. Harmonised standard updates have become a regular feature of the post-MDR landscape, reshaping the compliance baseline across affected product categories with each revision.
